Just read it in the news this morning (link to article, only in Croatian unfortunately):

Essentially, the Croatian AF will acquire 10-15 Mi-171Sh multi-puprose helicopters straight from the Ulan-Ude plant in Russia, as compensation for the former Soviet Union's debt to former Yugoslav countries. Final high-level negotiations are to start by the end of this month.

Of the total debt to Croatia, $65 million (roughly a third) are allocated for the helis. The "starting bid" is $7 million per helicopter and this includes spares, maintenance tools, test equipment, basic armament and crew training.

However, the AF is trying to negotiate more machines for less, and to equip them the best they can, given the $65 million limitation. Some additional modifications will be necessary, since the AF wants a type of navigation equipment (not specified in the article) that is not produced at the Ulan-Ude plant, and this will come out of the AF's own budget.

There are no specific dates, but the article states that the first helicopter will be due to arrive no more than 6 months after the start of production, with two additional being, I presume, ferried every 45 days.

The proposed machines will be virtually identical to the Czech airforce examples pictured below:

They're still produced, although with quite a number of modifications as compared to the originals.

The current production ones have a few different designations (Mi-8MTV-5 and Mi-17-V5 for transport versions, and Mi-172 and Mi-17KF for the pax ones), though most people (at least here) refer to them simply as Mi-171s. The "plain" Mi-17 designation belongs to the export version of the Mi-8MTV-1 (which is, in itself, the old production model).

All new-build Mi-17s (or Mi-171s or whatever they're called ) are externally distinguishable by the flat, as opposed to the old clam-shell, rear ramp. Internally, they're equipped with some Western avionics (including even a glass cockpit in some versions) and new engines, while some versions dispensed with the glass nose altogether and have a solid metal one housing the wx radar and some other avionics.

Quoting KC135TopBoom (Reply 2):I thought the only helios Mi is still building is the Mi-6 and Mi-26

The Mi-6 production was ended in the 80s already ! But of course, the is the Mi-28 which has been selected by the Russian army.
The Mi-24/35 is also still produced, but not only for the IAF. IAF, do you mean Indian Air Force ?

Essentially, to prevent confusion, here's the breakdown of all Mi-8 and beyond versions:

Mi-8T:
- the basic transport version
- TV2-117 engines, manufacture started in 1963.
- easily distinguishable, since the tail rotor is on the right side of the fuselage (the only version having this setup)

Mi-8MT:
- upgraded Mi-8T (M = modified)
- more powerful TV3-117 engines, tail rotor on the left for increased stability, marked air intakes and transmission from the Mi-14
- production started in 1975
